How are multiple departures from the same airport separated?

• A. Non-Radar separation
• B. Vertical separation
• C. Horizontal separation
• D. Radar separation

Answer: (A)

The concept being tested is how controllers ensure safe spacing when radar guidance isn’t used. When there are multiple departures from the same airport, they are separated using non-radar separation, a procedural approach that relies on timing, published routes, and altitude/speed constraints rather than radar positions. This method keeps aircraft apart through defined intervals or sequencing logic, which is essential in environments where radar coverage is unavailable or not employed for departure sequencing. Horizontal separation refers to lateral distance, and vertical separation refers to altitude differences, but these describe the type of spacing, not the method itself. Radar separation would use radar guidance to maintain distance, but the question focuses on the non-radar approach used for sequencing multiple departures.
